Abstract
In this study, application of the tissue reflectance spectrophotometry (TS-200) to the diagnosis of oral mucosa, was evaluated in the absorption intensity and the shape of the spectra of the gingiva of the rabbits. It is considered that the spectra obtained by TS-200 represent the hemoglobin absorbances and give information as to mucosal blood volume, average oxy- and deoxyhemoglobin equilibrium, and the tissue oxygen saturation. The measurements are given as value of H (hemoglobin concentration), value of A (oxyhemoglobin concentration), and value of F (O2 saturation).
The measurements were taken under the conditions with and without the resin plate and furthermore with and without the holder of the sensor during measurement. The following results were obtained.
1. There were the differences between the measurements in a day and another day before the plate insertion and also under the conditions with and without the resin plate.
2. The difference between the measurements under the conditions with and without the resin plate was greater than the one between in two days before the plate insertion.
3. The tissue reflectance spectrophotometry could be applied freehand to the diagnosis of oral mucosa under the denture.
